Description Sam Fowler 2019-08-05 23:59:58 UTC 
A third issue was discovered with the Kubernetes `kubectl cp` command that could enable a directory traversal such that a malicious container could replace or create files on a user’s workstation. The vulnerability is a client-side defect and requires user interaction to be exploited.

This vulnerability allows a malicious container to cause a file to be created or replaced on the client computer when the client uses the `kubectl cp` operation. The vulnerability is a client-side defect and requires user interaction to be exploited.
